Publication number: 20160191387Abstract: It is determined whether or not the address of a first type specified in an address resolution query is an address that allows direct routing to a first network. If the direct routing is determined to be allowed, a routing table is configured such that a packet including, as a destination, the address of a second type obtained by the address resolution query is forwarded to the first network. If the direct routing is determined not to be allowed, the routing table is configured such that a packet including the obtained address of the second type as a destination is forwarded to a second network.Type: ApplicationFiled: March 4, 2016Publication date: June 30, 2016Applicant: FUJITSU LIMITEDInventors: Masahiko TAKENAKA, Kunikazu Matsumoto, Daisuke Shinomiya, YUTAKA TAKAHASHI, Hiroaki SAKAI

Patent number: 9342637Abstract: A performance value DB stores multiple states of parts comprising a system, and the consumed power of parts in those states. In addition, a condition DB stores conditions when the states of the parts change. A calculator generates state sequences in which the states are arrayed in the order of change in accordance with conditions stored in the condition DB, when information indicating the states of the parts is not communicated. The calculator computes the percentage of the time the parts are in each state per unit time for each state comprising this state sequence. Furthermore, the calculator finds the products of the computed ratios and the consumed power stored in the performance value DB for each state comprising the state sequence, and estimates the sum of the products found as the consumed power of the part.Type: GrantFiled: September 14, 2012Date of Patent: May 17, 2016Assignee: MITSUBISHI ELECTRIC CORPORATIONInventors: Masashi Mori, Hiroaki Sakai, Yoshinari Sugegaya
